*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Riss River in Germany is a small tributary of the Danube, flowing through the state of Baden-Württemberg. Known for its serene and natural surroundings, the river is primarily fed by springs and rainfall, leading to relatively cool water temperatures. In winter, temperatures can drop to around 4-6°C (39-43°F), while in summer, they typically range between 15-18°C (59-64°F). These temperatures make the river unsuitable for swimming during colder months but can be refreshing in the summer for those seeking a natural spot.
Swimming in the Riss is not very common due to its small size, relatively cooler waters, and the fact that it is surrounded by rural and agricultural landscapes. However, there are some calmer areas where wading or a quick dip might be possible, especially during the warmer months. The riverbanks are more popular for walking and enjoying the peaceful countryside. Swimmers should exercise caution and verify if swimming is allowed in specific areas, as parts of the river may have environmental protections.
